( Figs 10A–C View Fig , 15F View Fig )

Type material: Holotype male: French Guyana, Caussade (52°35.29'W, 5°03.57'N), sampled by car-net, 7.11.2011, leg. T. Struyve ( UIC). GoogleMaps  

Paratypes: 1 male, 1 female with same data as holotype ( UIC, TSC) GoogleMaps   .

Etymology: The specific name was chosen to honour the collector T. Struyve.

Description: Length: 2.1 mm. Colouration: light brown; head and abdomen slightly darker than pronotum and elytra; legs and antennae yellow.

Head: 0.20 mm long, 0.35 mm wide; eyes large, but not prominent; longer than temples; fore-head semi-circular; setiferous punctation dense and coarse; on average, interstices between punctures half as wide as diameter of punctures; at middle of fore-head interstices slightly wider; netlike microsculpture weak; irregularly dense; surface shiny.

Antennae as long as head and half of pronotum combined; first antennomere thick and oval; second oval and slightly narrower and shorter than second; following antennomeres wider than long; sixth antennomere nearly three times wider than long; seventh antennomere thicker than sixth, but only 1.5 times wider than long.

Pronotum: 0.36 mm long, 0.39 mm wide; widest at anterior angles; evenly narrowed to posterior angles, but in posterior half stronger narrowed than in anterior half; posterior angles obtuse; nearly rectangular; lateral margin fine; visible throughout its total length; setiferous punctation coarse and dense; on average, interstices between punctures half as wide as diameter of punctures; wide midline impunctate; netlike microsculpture weak and irregularly dense; surface slightly less shiny than head.

Elytra: 0.45 mm long, 0.40 mm wide; widest in posterior third, but more or less subparallel; setiferous punctation weaker than on pronotum; netlike microsculpture weak and irregularly dense.

Abdomen with setiferous punctation; punctures as coarse as on fore-body; midline on tergites impunctate.

Protibia slender with few spines on outer edge; inner emargination distinct; in posterior aspect, comb visible throughout its total length; posterior face with long setae.

Aedegus thick; apical lobe in rectangular angle to basal lobe; apical lobe obtuse at apex; without paramera; endophallus slightly curved and divided into two branches.

Diagnosis: The differences are already given in the description of T. verhaaghi   .
